The sons of an _Aire desa_ were to wear clothes of a different colour every day, and of two different colours on Sunday, and to have both old and new clothes. The sons of the superior chiefs were to wear clothes of two colours every day, both old and new, and new clothes of two colours on Sunday; while the sons of the _Aire Forgill_, the highest of all, and of the king, were to have new coloured clothes at all times, and all embroidered with gold and silver. How far such regulations were ever practically observed may well be doubted, but those regarding food are probably enough. Porridge[217] was to be given to them all, but the materials of which it is made and the flavouring vary according to the rank of the parents of the children. The sons of the inferior grades are fed to bare sufficiency on porridge made of oatmeal and butter-milk or water taken with salt butter. The sons of chiefs are fed to satiety on porridge made of barley-meal, upon new milk with fresh butter. The sons of kings are fed on porridge made of flour, upon new milk taken with honey. The food of all, however, was alike, till the end of a year or of three years. The price of the fosterage of the son of an _Ogaire_ is three _Seds_ or three _Samhaiscs_, that is, three-year-old heifers; and for his daughter four _Seds_, a _Sed_ in addition being given for the daughter, because the household arrangements for her accommodation are more extensive than for the sons. This was the lowest price given, and the _Fer Midbuid_, or man of the humblest rank, could not perform the fosterage for less. The boys were to be taught the herding of lambs, calves, kids, and young pigs, and kiln-drying, combing, and wood-cutting; and the daughters the use of the quern, the kneading-trough, and the sieve. The price of the fosterage of the son of a _Boaire_ was five _Seds_, or three cows. The price of the fosterage of the son of an _Aire_ was ten _Seds_, and instruction in the usual sciences is given him; that is, the sons were taught horsemanship, _brann_-playing, shooting, chess-playing, and swimming; and the daughters sewing and cutting-out, and embroidery. The price of the fosterage of the son of a king was thirty _Seds_, and the foster-sons were to have horses in time of races, and the foster-father was bound to teach them horsemanship.
